There are red bars meaning those parts had errors, with the grey idicating what was successfully retreived..

Looking at the date which makes those posts about 60 days old I would guess that the posts are on the edge of retention and have started expiring off the server. As far as I know PowerUsenet does not offer 60 days retention?

Receiving a 430 error means NewsBin is downloading using a message ID and the server does not have the post. In this case, it looks like you loaded an NZB file and the files were originally posted to usenetserver. It could be that usenetserver has not propagated these files to other servers yet.

I've emailed there tech support about this issue. cause I'm sseing it more & more with differnt posts

I thought it might be a NZB so I downloaded all 5 million headers looking for the files that were in the NZB and the same result even though Power Usenet shows them as complette there not.. it downloads all the file except for a few 100k of it
and then greys out & goes to the next one and does the same thing

I've been seeing the same as Phil the last couple days. At the moment I can't even bring up powerusenet.com. Just now I managed to download 240k and then it up and quit. Newbin is now reporting the stuff pasted below. May the all mighty router that died rest in peace.

I'm seeing the same problem, but its only on new posts. basically, the headers say they have completion, but they are repeatedly failing on certain individual posts (i.e. one per file I try to download), sometimes after many retries it fetches it.

However, on older posts, there seem to be no problem. I'm not so annoyed, as haven't had anything I can't fix through pars.

Same story here. Lots of incompletes and droped connection. I emailed them tonight asking WTF. No reply yet. I will give them till tomorrow and see what kind of an answer they come up with before I shop around.
